SeaFrogs 40M/130FT Waterproof camera housing for Sony A7 IV + Optical acrylic 8" Dome port V.8 only (Standard or Flat port not included).

The Sea Frogs A7 IV Salted Line series camera housing in black ensures water resistance up to 40 meters (130 feet) and is expertly designed for the Sony A7 IV. This configuration includes a bundled 8-inch optical correct acrylic dome port V.8. Notably, the Seafrogs 8' dome port V.8 features the shortest extension adapter ring available, measuring a mere 23mm long. Compatible lenses are listed below.

SeaFrogs Salted Line A7 IV housing lets you control all camera functions (except the joystick and Still / Movie / S&Q dial) underwater up to 40 meters (130 feet). The standard bayonet with a 90mm diameter allows for using any Sea Frogs dry flat and dome ports, except ports designed explicitly for A6xxx and RX1xx camera housings.

The Salted Line A7 IV version stands out from the standard Sea Frogs A7 IV housing with enhanced features, including two stainless steel latches with locking pins, a larger LCD window, and the capability to mount a detachable 2-stage pistol grip trigger. Notably, the control buttons boast a 50% increase in spring stiffness, ensuring improved tactile feedback. Ideal for underwater and surf photography, this upgraded housing offers enhanced durability and precision for Sony A7 IV users. Explore the advanced capabilities of the Salted Line A7 IV housing for an optimized underwater shooting experience.
